might I do something bad, the way I update my stimuli? Before entering the main loop I do: - preloaded_texture_list = [] # empty at first for stim_index in range(num_images): # Read the texture file texture = Texture(photoX[stim_index]) # Add to list of stimuli preloaded_texture_list.append( texture ) stimulus = TextureStimulus(on = 1, texture = preloaded_texture_list[0], size = preloaded_texture_list[0].size, lowerleft=(x,y)) viewport = Viewport( screen=screen, stimuli=[stimulus] ) - in the main loop: - stimulus.parameters.texture = preloaded_texture_list[stim_index] screen.clear() viewport.draw() swap_buffers() - should I increment my stimulus in another way.Do I assign to much memory this way? please help me!!! christoph -- Christoph Lehmann <lehmann@xxxxxxxxxxxx> University Hospital of Clinical Psychiatry ====================================== The Vision Egg mailing list Archives: //www.freelists.org/archives/visionegg Website: http://www.visionegg.org/mailinglist.html
