From 8550c2b594fb1a2544b77b7f3abec84b29b1745d Mon Sep 17 00:00:00 2001 From: Benoit Bolsee Date: Wed, 1 Oct 2008 19:16:13 +0000 Subject: BGE patch: new force field constraint actuator A new type of constraint actuator is available: Force field. It provides a very similar service to the Fh material feature but with some specificities: - It is defined at the object level: each object can have different settings and you don't need to use material. - It can be applied in all 6 directions and not just -Z. - It can be enabled/disabled easily (it's an actuator). - You can have multiple force fields active at the same time on the same object in different direction (think of a space ship in a tunnel with a repulsive force field on each wall). - You can have a different damping for the rotation. Besides that it provides the same dynamic behavior and the parameters are self explanatory. It works by adapting the linear and angular velocity: the dynamic is independent of the mass. It is compatible with all other motion actuators. Note: linear and anysotropic friction is not yet implemented, the only friction will come from the object damping parameters. Support for friction will be added in a future revision. --- source/blender/src/buttons_logic.c | 40 +++++++++++++++++++++++++++++++++++++- 1 file changed, 39 insertions(+), 1 deletion(-) (limited to 'source/blender/src/buttons_logic.c') diff --git a/source/blender/src/buttons_logic.c b/source/blender/src/buttons_logic.c index ba8116dbc5b..052bf3f1ae4 100644 --- a/source/blender/src/buttons_logic.c +++ b/source/blender/src/buttons_logic.c @@ -2214,8 +2214,46 @@ static short draw_actuatorbuttons(Object *ob, bActuator *act, uiBlock *block, sh uiDefButS(block, NUM, 0, "time", xco+10, yco-84, 70, 19, &(coa->time), 0.0, 1000.0, 0, 0, "Maximum activation time in frame, 0 for unlimited"); uiDefButF(block, NUM, 0, "min", xco+80, yco-84, (width-115)/2, 19, &(coa->minloc[0]), 0.0, 180.0, 10, 1, "Minimum angle (in degree) to maintain with target direction.
